UNIT

Syntax

UNIT ( expression )

Implemented in iMath since version 2.2.0 or earlier.

Explanation

Try to find a quantity (number with optional units) for the expression from any equations defined previously in the document, and then get the units of this result. Gives an error if the expression does not evaluate to a quantity.

Example

EQDEF a = 3 x

EQDEF b = 2 x

EQDEF x = 7 %metre

EXDEF UNIT(a + b)

This will output "m".
